2. DESCRIPTION OF THE FUNCTIONS
The keyboard of the Thermohygrometer HD2301.0R is composed of double-function keys. The
function on the key is the "main function", while the one above the key is the "secondary function".
When the instrument is in standard measurement mode, the main function is active.
In the menu, the secondary function is enabled; press the DATA+UNIT keys together to open the
menu.
The pressing of a key is accompanied by a short confirmation "beep": a longer "beep" sounds if the
wrong key is pressed. Each key specific function is described in detail below.
This key has two functions:
ON/OFF: to turn the instrument on press ON, to turn it off press OFF.
The turning on enables all display segments for a few seconds, starts an Auto-test including the
detection of the probe connected to the input, and sets the instrument ready for normal
measurement. The following is displayed:

AUTO/OFF: the AutoPowerOff function can be disabled by simultaneously pressing this key
and the "HOLD" key when turning the instrument on.
During turning on, should no probes be connected, the "NO_PRBE_SER_NUM" message is
displayed in the line for symbols for a few seconds, and in the main line a series of dashes appears
while the "ERR" message replaces the temperature.
When the probe is inserted into a functioning instrument, the "NEW_PROB_DET" (New probe
detected) message appears: as the data are captured upon turning the instrument on, it is necessary
to turn it off and on again.
Caution! Replace the probes when the instrument is off.
The instrument has an AutoPowerOff function that automatically turns the instrument off after about
8 minutes if no key is pressed during the intervening time.
At the switching on, press simultaneously the ON/OFF key and the HOLD key to disable this
function.
